Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Pulse width (µs)

Servo control pulse width in microseconds.

Map a hobby servo pulse width between 500 and 2500 microseconds to a signed angle with the documented linear scale of 1000 to 2000 microseconds covering -90 to +90 degrees, clamping extended-range pulses to the endpoints. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Angle (°)

Commanded angle clamped to the -90 to 90 degree range.

• Pulse width, angle, speed, and step relationships depend on controller convention, gearing, microstepping, load, supply, deadband, mechanical stops, acceleration, missed steps, and calibration. Commanded position is not necessarily achieved position.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Servo Pulse Width From Angle

  Interpolate a hobby servo command pulse width from angle using the servo's calibrated angle and pulse-width endpoints; do not assume a universal pulse range.

• ADC LSB Voltage

  Calculate one ideal ADC code width as full-scale input span divided by 2^N. Full-scale span is the high-to-low range, not necessarily the reference voltage for every ADC topology.

• Antenna Polarization Loss

  Ideal linear-polarization mismatch loss from the relative angle between transmit and receive polarization axes.
